Pleomorphic adenomas of the parapharyngeal space.

Akın I, Karagöz T, Mutlu M, Sahan M, Onder E - Case Rep Otolaryngol (2014)

Bottom Line: Case Presentation.Here, three giant pleomorphic adenomas of different sizes occupying the parapharyngeal space in three patients are reported.The excision of the tumor through submandibular transcervical approach, without cutting the mandible, turned out to be a safe and radical approach in all three cases.

ABSTRACT
Background. Parapharyngeal space is one of potential facial planes for neoplasms and infections and represents less than 1% of all head and neck tumours. Occurrence of the pleomorphic adenoma in the parapharyngeal space is a rarity. Case Presentation. Here, three giant pleomorphic adenomas of different sizes occupying the parapharyngeal space in three patients are reported. Extensive preoperative diagnostic workup was done in order to verify the nature and size of the tumour and the proximity to the large vessels. Review of the literature, clinical features, pathology, radiological findings, and treatment of these tumours are discussed. Conclusion. The excision of the tumor through submandibular transcervical approach, without cutting the mandible, turned out to be a safe and radical approach in all three cases.

fig2: Intraoperative and gross feature of the mass.

Mentions: On intraoral examination of the patient, there was a firm bulging of the left soft palate and left lateral pharyngeal wall crossing the midline and pushing the uvula to right side along with a smooth overlying mucosa. Digital palpation of the left tonsil was felt to be firm as well. Although the nontender lesion of the patient caused a considerable degree of dysphagia, no major complaints were reported. He had no fever and denied soreness of his throat. The mass pushing the left tonsil towards the midline of the oropharynx was extended from the left side of nasopharynx to the oropharynx. Externally, there was a swelling in the left submandibular region. Clinical examination did not reveal involvement of any of the cranial nerves. With a clinical diagnosis of parapharyngeal space tumour CT and MRI scan were taken which showed homogenously enhancing tumour measuring 5 × 4 cm in the left parapharyngeal space (Figure 1). Fine needle aspiration cytology of the mass in the neck was consistent with benign mixed tumour. A transcervical approach was used to gain access to the left parapharyngeal space without any mandible osteotomy. The tumour was completely excised. On gross examination the lesion was 9 × 6 × 2.5 cm (Figure 2). Histopathological examination showed a neoplasm having an admixture of epithelial and stromal components (Figure 3).
